Dow Jones is reporting that Navistar is running out of pollution credits for use in California. The California Air Resource Board issued an executive order covering the sale of engines produced up to Feb. 29, 2012. (See below for PDF of the order.)
In another development, a federal judge dismissed Navistar's lawsuit against the EPA that called for a recall of 2010 engines using selective catalyst reduction. Navistar competitors use this technology.
